Building WHERE or HAVING Clause

When retrieving data, you may want to set up a filtering expression or relation between tables. You can do it using WHERE and HAVING clauses. Refer to SQL manual to learn what’s different in these sections. In Query Builder for SQL Server visual interface for WHERE and HAVING clauses is the same.

In the tabbed editor conditions are displayed as a tree with condition and group nodes. A group consists of several conditions or subgroups, united with a logical operator. You can change a group logical operator by clicking it and selecting another one from the menu. To navigate between conditions and groups, use the UP ARROW and DOWN ARROW keys. Use the LEFT ARROW and RIGHT ARROW keys to navigate between criteria operator and operands.

To create a new group, do one of the following:

  • Click the upper-level group operator and choose Add Group from the appeared menu.
  • Press CTRL+PLUS SIGN.
